"While only a product refresh, Samsung has squeezed a bit more performance out of their new Portable SSD T5's. A new ASMedia controller enables USB 3.1 Gen 2 for those with a capable port, pushing speeds upwards of 540 MB/s, while those with 'older' USB 3.1 Gen 1 ports will still enjoy the ~450 MB/s seen with the T3 and T1. The extra 100 MB/s may not be groundbreaking, but it certainly comes in handy when waiting for larger files to transfer. Overall I was happy with the fit, finish, aesthetic, and performance of the T5, and it, therefore, becomes my new default recommendation for those demanding a lot from their portable storage while on the go."
